17. Electronic Configure To Order (ECTO) Control Parameters
Many M2 main control operations may be varied within a set range. Default settings are based on common or average ap-
plications; change ECTO settings only when custom applications, preferences or local building codes exist. Default, mini-
mum, and maximum range settings are found in table 41.
Failure to perform the following steps may result in unsatisfactory unit operation.
1. Prior to changing ECTO's, unplug the Novar phone cable to M2 sysbus.
2. When ECTO changes are complete, return DB1 to DISPLAY mode and reconnect the Novar phone cable.
ECTO parameters may be changed two different ways:
S
using the Prodigy Display
S
using an optional PC Unit Controller (UC) software
17.1. Using the Prodigy Display
Set ECTOs using Prodigy menu, SETTINGS > CONTROL > ECTO. Refer to the Prodigy Installation and Setup Guide.
The parameters are set up in ten different blocks or groups. The first digit of each parameter indicates the block as follows:
0− VAV/CAVB
1− heat pump heating
2− electric heating
3− gas heating
4− cooling
5− miscellaneous
6− system 1
7− system 2
8− system 3
9− GP board
An M2 board configured for a gas heating unit will skip heat pump block 1 and electric heating block 2 readouts. An M2 board
configured for an electric heating unit will skip heat pump block 1 and gas heating block 3 readouts. An M2 board configured
for a heat pump unit will skip electric heating block 2 and gas heating block 3 readouts.
17.2. Reset To Factory ECTO Parameters
To restore the factory ECTO parameters, refer to the Prodigy Installation and Setup Guide.
17.3. Unit Controller PC Software
The L connection unit controller PC software is recommended when adjusting multiple ECTO parameters. Unit controller
PC software allows the user to adjust parameters using real units (no conversion from display readout). PC software is faster
than using the pushbutton/display interface on the M2 board.
In addition, the PC software allows the user to save unit configuration files. The saved file can be used to apply the same
settings to other units.
